CRERRETE ADMETESzakhala zikugwiritsidwa ntchito konkriti pafupifupi zaka zana limodzi ngati chinthu. Koma kukhala pachibwenzi kalelo, kwenikweni, anthu akhala akudziwa kale kugwiritsa ntchito zowonjezera pomanga zida zomanga. Zolemba zotsimikiziridwa zomwe m'ma 1885 azungu amadziwa kale kuti oyang'anira magetsi, monga laimu ndi gypsum, adanjezedwa konkriti. Kumapeto kwa zaka za zana la 19, kugwiritsa ntchito calcium chloride kunali mkwiyo ndipo kumagwiritsidwa ntchito masiku ano. Podzafika mu 1895, okulitsa madzi ndi ma pulasitala ndi ma pulasitiki awonjezeredwa konkriti kwa msewu, zomwe zimathandiza bwino kukhazikika kwa konkriti.
Zogulitsa zamafakitale zidawonedwa koyamba mu 1910. Pamene North America idapangidwa ku United States m'ma 1930s, kutsitsa konkriti kunazizira chifukwa cha nyengo yozizira kwambiri. Pofuna kusintha konkriti ya konkritiyo, "Visili sain" idagwiritsidwa ntchito kukonza chizunzo cha konkriti. Kugonana. Kafukufuku weniweni wa sayansi ndi "pozzolitn" wothandizira (Pozzolitn), womwe unkafufuzidwa bwino ndikupangidwa ndi ew scxiptter ya United States mu 1935, komwe kumapangidwa ndi lignosulfonate mu zamkati. Mu 1937, United States idapereka patent yoyamba yosungirako madzi m'mbiri yonse. Mu 1954, gawo loyamba la miyezo yoyesereraCRERRETE ADMETESanapangidwa.
Kugwiritsa ntchito mwalamuloCRERRETE ADMETESM'dziko langa linali m'ma 1950s. Panthawiyo, ntchito ya Rosin Sponational Office yomwe idapangidwa ndi akatswiri ochokera kwa Soviet Union idayambitsidwa. Inagwiritsidwa ntchito ku Tianjin Tanga New Down, Wuhan Yangtze mtsinje wa Bridge ndi Sturchvoir, ndikukwaniritsa zotsatira zina. Pambuyo pake, mafayilo a ma Crediver a Conp amagwiritsa ntchito zinyalala zamadzimadzi kuchokera ku sulfa pepala ndikuwononga uchi kuchokera ku shuga ndi zinthu zopangira zidagwiritsidwa ntchito. Kugwiritsa ntchito ma Adntactureture kunayambiranso kuchokera pamenepo.
Chitukuko ndi kugwiritsa ntchitoCRERRETE ADMETESikufunika kwambiri. Kukula mwamphamvu ndikulimbikitsa kugwiritsa ntchitoCRERRETE ADMETESndi njira yofunika kwambiri yolimbikitsira kupita patsogolo kwa sayansi kwa makampani omanga.
M'zomangamanga pantchito zomanga, kugwiritsa ntchito ma Adminictures kumatha kukonza bwino malo omanga, kuthandizira kugwiritsa ntchito zida zosiyanasiyana zopangira, kuchepetsa ntchito zomangamanga, ndikuwonetsetsa kuti ntchitoyo yomanga. Kuphatikiza apo, imatha kugwiritsidwanso ntchito pamavuto ena. Malizitsani bwino ntchito zomangamo.

Tifupikitsidwa kwambiri. Nthawi yomweyo, kuwonjezeraCRERRETE ADMETESItha kusinthanso bwino ntchitoyo, ndikusintha mphamvu yake, kukhazikika, kukana chisanu, komanso kufooka.
Kuphatikiza apo, imatha kusintha kwambiri ma scewte pomwe imawuma mokwanira komanso kayendedwe ka kayendedwe kazinthu zisanakhazikitsidwe. Ngati kuphatikiza konkriti kumagwiritsidwa ntchito moyenera m'ntchito yomanga Kuchepetsa kugwiritsa ntchito zida zothandizira simenti sizimangopulumutsa ndalamazo, komanso zimapulumutsanso mtengo womangawu, ndipo zimakhudzanso njira zotsatirazi. Njira yolowera komanso yopondera imapereka mwayi.
